Available sildenafil strengths

Sildenafil is commonly supplied in three main strengths:

• 25mg
• 50mg
• 100mg

Each strength may be suitable for different individuals depending on their health, age and response to treatment.

A consultation helps determine the most appropriate starting dose.

Sildenafil 50mg (standard starting dose)

For many patients, sildenafil 50mg is the usual starting dose. It provides effective support for erectile dysfunction while allowing assessment of how well the treatment works.

The dose may be adjusted depending on effectiveness and tolerance.

Patients can learn more about treatment options through a professional consultation.

Sildenafil 100mg

Some individuals may require a higher dose if the 50mg strength is not sufficiently effective. Sildenafil 100mg may be considered following professional assessment as part of a structured erectile dysfunction treatment plan.

A healthcare professional will determine whether a higher dose is appropriate based on medical history and response to treatment.

Higher doses may increase the likelihood of side effects, so medical guidance is important.

Sildenafil 25mg

A lower starting dose such as sildenafil 25mg may be recommended for individuals who are more sensitive to medication or have certain health conditions.

A lower dose may reduce the likelihood of side effects while still providing benefit.

How to take sildenafil

Sildenafil should usually be taken approximately 30 to 60 minutes before sexual activity. It should be swallowed with water and can be taken with or without food, although heavy meals may delay its effect.

Important guidance:

• Do not take more than one dose in 24 hours
• Follow dosage instructions provided
• Avoid excessive alcohol before use
• Allow time for the medication to work
